Resistance training appears to restore physical strength, immune health in frail or at-risk cancer survivors https://t.co/MaEVMNOhWn via @medical_xpress
Aerobic exercise is not background “cardio” in cancer care.
It is a therapeutic intervention.
In the latest article in my Substack series, Exercise as Medicine in Oncology, I examine why aerobic exercise is an essential modality in exercise oncology.
Aerobic training improves the integrated function of the heart, lungs, blood vessels, blood, and skeletal muscle mitochondria. That matters because cancer and its treatments can impair oxygen delivery, vascular function, mitochondrial efficiency, metabolic control, immune regulation, and cardiovascular health.
In this article, I discuss:
• why cardiorespiratory fitness is a powerful clinical marker
• how aerobic exercise reduces cardiovascular disease risk in cancer populations
• how aerobic training influences tumour perfusion, oxygenation, and treatment delivery
• why mitochondria matter for fatigue, oxidative stress, and possibly cognitive function
• how aerobic exercise supports immune mobilisation and inflammatory regulation
• why MICT, interval training, HIIT, aerobic circuits, and HIRT each have distinct roles
The key point is simple:
Aerobic exercise must be prescribed, not generalised.
The question is not whether a patient should “do cardio.”
The question is what aerobic stimulus is required, how it should be delivered, and how it should be adjusted to treatment, symptoms, and clinical goals.
This article draws on the framework developed in my book, MyExerciseMedicine for Cancer.

Muscle loss with age is common, but much of that decline is driven by inactivity, not aging alone.
On average, we reach peak muscle mass somewhere between 20 and 30, then lose about 8% per decade after that. By the time many adults reach their 70s and 80s, they may have only 60–80% of the muscle mass they had at 30.
A big reason why is anabolic resistance. As we get older, muscle becomes less responsive to amino acids, one of the key signals for building and maintaining muscle.
This is where resistance training becomes non-negotiable. It's one of the main signals that tells muscle to grow. And just as importantly, it helps re-sensitize muscle to amino acids, so the body responds to protein more like it did when you were younger.
